Anybody know how to use auth_to_local with Redhat's Kerberos?

[Scott Simpson]

I running Redhat 4 which uses Kerberos 1.3.4. I'm trying to get the 
"auth_to_local" rule working in the [realm] stanza. If I set

auth_to_local = DEFAULT

it works fine. But if I set it to

auth_to_local = { DEFAULT }

it comes up but doesn't work. If I set it to

auth_to_local = {
    DEFAULT
}

I get a syntax error and krb5kdc won't even come up. Any help would be 
appreciated. Thank you.
